TO ALL WHOM IT MAY CONCERN: y

Be itknown that I, EDWIN L'. BERGSTRESSER, of I'Inblersburg, Centre county, State of Pennsylvania, have invented new and useful improvements in Self-Baker for Harvesting Machines; and I do Ihereby declare the following to be a clear, and exact description thereoi', reference being had to the accompanying drawings,

and to the letters of reference marked thereon, making a part of this specification, in whieh- Figure 1 represents a top view of the platform and .ral-re; and Fig-tire 2, an underside View.

My invention consists in the shape of the teeth; the hinged slatsl forming the platform and the travellingrake-head.

A represents the front of the machine where the knives operate; B,'the square frame; C, the rake-head underneath the platform, and operated hy an endless belt D', E, the teeth forming the rake, which are `fastened. to the rake-head, and move erect across the platform, passingv between the slats G,.flrawing theisheaf with them until the sheaf is thrown o' at'the one end ofthe platform; and the bent lever P (permanently attached to tho rake-head) comes in contact with the bent stop S at thc end of the platform, when the teeth E fall and pass through the apertures H, and under the slats,l back again to the l'opposite end of the platform, nntilthe bent lever P comes in Contact with the opposite bent stop 'l, when the teeth E, at the saine time, raise the slats Cr until the teeth E pass upward-f through the openings or oil'sets W at the ends of the slats G, and the teeth eom-` menee t-o rake or carry ot`t` the grain. I'he middh.I teeth E are bent at an angle at their outerends tu assist in raising the slats G. 'The outer teeth are straight, and not bent at the top, as seen at J. The centre slat K is stationary, but the outer slats Cr are hinged at the inner end, so that, as the teeth raise the slats at their opposite ends, they assist, by their inclination, in throwing,r oli` the sheaf.

What I claim as mjy-invention, and desire to secure by Letters Patent,

1. The lhinged slats of `lche platform, arranged so as to riso and let the teeth pass up, and also assist in carrying the sheaf ofi', as herein described.

2. I also claim the construction and arrangement of the rake-teeth so as topess under or in the platform at one end thereof, and raisethe free ends of the hinged slats as they riso at the other end, to carry nii' thel sheaf. 3. I also claim the combination of a platform, provided with two or more hinged slats and au automatic reexproeating rake, substantially as herein described, and for the purposes set forth.
